Hi, ahetz!

So that the Community can help you better, we will need to know exactly which version of Mac OS you're using on your iMac, and which apps you're trying to print from. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, our US-based technical support team is standing by, ready to help 24/7 via Email at http://Canon.us/SupportCF or by phone at 1-800-OK-CANON (1-800-652-2666) weekdays between 8 AM and 8 PM ET (5 AM to 5 PM PT).

Thanks and have a great day!
